  • a Pearson correlation coefficients from pairwise comparisons of rep-PCR fingerprints between strains.

  • b m/n for pairwise comparisons of enzyme electrophoretic mobility polymorphisms between strains, wherem is the number of mismatched loci and n is the total number of loci evaluated by MLEE using 38 metabolic enzymes (23).
